When I start a new competitve game in CSGO, my fps is above 150, but the fps drop durng the game. After 10 minutes it's around 100 fps, and after 15 minutes it's aroud 50 fps. I need to close the game and reconnect to recover my 150 fps. This problem is since my last CCC update (i now have 15.7.1). Do you know what I can do to solve the problem?
